Title: Water in Space
Post by: vhfpmr on 07/06/2023 16:02:25

I've lost count of the number of times I've seen them playing around with stunts like this, why the hell aren't they fazed about thousands of water droplets floating around in the air and getting into the electronics?

Dunno what you are after, but comets are known to be composed of a large percentage of water.

But what's that got to do with astronauts messing around splashing water all over the place inside the space station?

This is Intriguing.
Moisture & Oxygen content might be high on ISS.
Corrosion occurs on Earth.
Wonder how They manage to tackle the issue up there.
Is the whole ISS waterproofed or something?

Oh. I think that the connections must be protected from water, the condensation would be problematic if not, pooling and subsurface water must be a problem.

There won't be  any condensation on the space station, their water supply comes from reprocessing expired (and excreted water). There's no mains water supply up there.

There is some water vapour in the air, to make breathing more comfortable (I understand 30-50% is ideal for humans).
There will be some parts of the space station that get cool (because the outside is shielded from sunlight), so condensation could happen (but they would try to minimise it!).

There's condensation in a typical kitchen too, but not to the degree that all the electronics need sealing to IP65. That might be different if you were deliberately throwing water splashes over your kitchen TV though.

They had to make space station electronics sneeze-proof.

Follow up Query...

What about Farts?

Perhaps some sort of air circulation filters might be installed, isn't it.

I believe it's a nasa patent

Hmm...Weird!

Patent Laws apply out of the World too eh?
